To all whom it may concern:

Be it known that we, EMEBY T. EPLIN and CHARLES WoELrLEN, citizens ofthe; United States, residing. in the city of Lewiston, county of NezPerces, State of Idaho,

have invented certain new and useful "Improvements in Fastening Devices,of which that the closing of the buckle acts to draw the strap moretightly around the trunk or other object around which the strap extends;

to provide a construction in which the pull on the buckle is below thecenter of resistance of the hinge or pivot so as to obviate any tendencyfor the buckle to open on direct pull or strain on the strap; to providea construction in which the buckle can be released by merely lifting thefree end of the strap and without any strain or exertion, but whichnevertheless will not of itself loosen or unbuckle; to provide aconstruction in which the free end of the strap can be easily andreadily secured to the tongues of the buckle and still the strap bedrawn tightly around the trunk or other object because of the leverageaction of the free arm of the buckle heretofore referred to; to providea construction in which the main arms, of the buckle may be cheaplyformed from relatively small metal stampings and the looking parts bysimple rivets; to provide a construction which is efficient in operationand yet simple and economical of manufacture; and in general, to providean improved construction of the character referred to.

The invention consists in the matters hereinafter described and moreparticularly pointed out in the appended claim. 7

In the drawings Figurel. is a perspective view of the invention shown inopen-or unlatched position with a part of the strap broken out to reducethe size ofthe drawing. Fig. IT. isa view similar to Fig. I. butshowingthe free end of the strap in place on the movable or look arm ofthe buckle. Fig. III. is. a similar view but showing the buckle closedaround the free end of'the strap. Figs. IV. and V. are detail views ofhe locking finger or turn buckle taken at ight angles to each other.

In the drawings, 1 designates a leather strap or other flexible fastenerwhich is provided at one end with a series of buckle holes 2 and at itsother end is riveted as shown at 3 to the relatively stationary arm 4:,the other arm 5 of the buckle is hinged or pivoted as shown at 6 to theadjacent end of the arm 4C. In order tohold the strap more securely tothe arm 4:, the latter has its upper edges 6 turned or crimped down overthe edges of the strap as shown clearly in the drawings. The free end ofthe arm 4L- has upturned flanges or ears 7 and to these ears is securedby pintles 8 a U shaped metal strap 9. These pintles 8 preferably takethe form of rivets and on them is pivotally mounted the fork end 10 ofthe lock arm 5. This fork end 10 is formed by cutting away the adjacentflat portion of the arm 5 and bending it back upon itself as shown at 11and there riveting it in place by rivet 12. This rivet 12 projectsthrough the arm as shown clearly in Fig. I. and forms one of the buckletongues to which the free end of the strap 1 is detachably secured. Thesides 13 of the arm 5 are turned in to form flanges, thus making the armsubstantially channel shaped. The free end of the arm 5 is provided witha lock tongue 14. This tongue 14: is pivotally mounted in the outer endof the arm 5, is provided at its inner end with a slightly elongatedhead 15 and at its outer end with a thumb lever 16, the constructionforming in effect a turn button. The headed end 15 is adapted to passthrough a similarly elongated aperture 17 cut through the confined endof the strap 1 and the arm 4:. The arrangement is such that when theheaded end of the turn button is in the position shown in Fig. I. itwill pass through the hole 17 as the arm 5 fits over the arm 4. The twoarms are thus locked in position by turning the headed end so that itwill not pass through the hole 17.

The operation of the device is apparent from the foregoing description.To look the fastener around a trunk or other object, the buckle isopened to the position shown in Fig. I. and the free end of the strap isthen passed between the forked end of the arm 5 and pulled up tightlyand the apertured end of the strap pressed down over the tongues 12 and14:. 'The arm 5 is then swung over jects through "the "hole 17 whenthe'thumb their ends and adapted to lie fiat'upon each lever is turned andthe buckle locked; It other when in folded position, one of said isappai'ent- 'thatvthe meretu-rning down of arms having a strap connectedthereto, a 15 the arm 5 over the arm 4 acts as a lever to buckle tongueon the inner face of said other 5 pull the strap more tightly aroundthe" arniforreceiving the free end of said strap trunk. 7 I p and a turnbutton for locking said arms in Y The inventioni is not limited to'thedetails folded position. shown except as set forth -in-the appendedEMERY T.
